Volvo downsizes engine for the future

Gothenburg wants to be greener than green

Swedish carmaker Volvo has a reputation for being eco friendly and their latest initiative towards zero emissions through a new, downsized engine range consisting solely of four-cylinder petrol and diesel engines.

"It's time to stop counting cylinders. At the Frankfurt Motor Show we will reveal a new concept car. It proves that downsized engines can go hand in hand with our customers' expectations on luxury and driving pleasure," says Peter Mertens, Senior Vice President Research and Development at the Volvo Car Corporation.

The Volvo Car Corporation's upcoming four-cylinder VEA (Volvo Environmental Architecture) engine range includes common rail diesels and direct injected petrol engines. It covers the whole range from high power and torque variants to fuel-efficient derivatives.





"Our four-cylinder focus is the perfect way for us to quickly reduce CO2 emissions and fuel consumption. We will develop four-cylinder engines with higher performance than today's six-cylinder units and lower fuel consumption than the current four-cylinder generation," continues Peter Mertens.

The new VEA engines reduce the number of unique parts by 60 percent. The new powertrains are also up to 90 kg lighter than the present ones and fuel economy is improved by up to 35 percent.

Later this year Volvo will test the potential of KERS (kinetic Energy Recovery System  on public roads.
The device captures braking energy in a flywheel that spins at up to 60,000 revs a minute. Once released, this stored energy can either accelerate the car or propel the vehicle once it reaches cruising speed.

"The flywheel system offers the driver an additional 80 horsepower while reducing fuel consumption by up to 20 percent," says Peter Mertens.

With the company still facing dire financial situation, Volvo is also working hard on a new way of building cars called SPA (Scalable Platform Architecture). SPA allows most Volvo models to be built on the same production line irrespective of vehicle size and complexity.

"We're taking our technological future into our own hands. Both our new architecture and the new engine range will enable us to be on par or even beat our toughest competitors in crucial areas such as driving dynamics and fuel economy," says Peter Mertens.

In addition to the industrial benefits of common vehicle architecture there are also significant product-related advantages. The Volvo Car Corporation will take the lead in automotive lightweight design with upcoming SPA models being 100-150 kg lighter than current models of the same size.
The new architecture enables electrification at all levels - and new chassis technologies combined with the lower weight and improved weight distribution will boost driving dynamics.
The new concept car unveiled next week in Frankfurt also shows that SPA offers the Volvo Car Corporation's design team greater freedom to give forthcoming Volvo models more exciting looks.
"The new architecture means we can sharpen our design language, carving out just the right athletic and dynamic aura that is so important to the most demanding prestige car buyers. The Frankfurt concept car is a great example of what we can achieve with the new architecture," relates Peter Horbury, Vice President Design at the Volvo Car Corporation.
